Infant formula: EU tightens checks, US botulism cause unclear, liver disease link found #food

The European Union has increased scrutiny of arachidonic acid oil imports, particularly from China, due to contamination concerns in infant formula. This follows a botulism outbreak in the US linked to baby formula, the cause of which remains under investigation. Separately, research indicates that the type of fats used in some infant formulas may contribute to early-stage liver disease. ## Latest Update Mayo Clinic researchers have identified a rare genetic mutation in the MET gene that can directly cause metabolic dysfunction-associated steatotic liver disease (MASLD). This mutation disrupts the liver’s ability to process fat, leading to inflammation and potential liver failure, offering a new target for therapies. ## Timeline * **2026-02-27:** EU tightens checks on arachidonic acid oil imports due to contamination concerns in infant formula. * **2026-02-28:** US health authorities declare the botulism outbreak linked to a baby-formula maker to be over, but the cause remains under investigation. * **2026-02-28:** Research suggests a potential link between certain fats in infant formulas and the development of early-stage liver disease. * **2026-03-07:** Mayo Clinic discovers a rare mutation in the MET gene that can directly cause metabolic dysfunction-associated steatotic liver disease (MASLD). ## What to Watch * **Supply Chain Disruptions:** Further tightening of import regulations could lead to shortages or price increases in infant formula. * **Regulatory Action:** Expect further investigations and potential recalls related to infant formula safety in both the EU and US. * **Health Impacts:** Monitor research on the long-term health effects of different infant formula compositions, particularly concerning liver health.
